Abstract

PURPOSE:To improve the operability of a display system by displaying desired pictures of respective modes while various modes are selected, and displaying an updated picture when a new mode is set after a display picture is updated. CONSTITUTION:A mode switching means A selects an automatic operation mode, a tape operation mode, an editing mode, a manual mode, etc., through an operator. A specified picture number selecting means B selects and outputs the number of a picture displayed for each switched mode automatically. A picture number switching command means C is operated when a display picture is updated and provided normally on a keyboard. When the update of the picture is commanded, a picture update judging means D judges whether or not the number of the picture is new and outputs an update command when correct to switch the contents of the specified picture number selecting means B to a new display image, so that the updated picture is displayed automatically. Consequently, the operability is improved.

Description

[Detailed description of the invention] (vl essential) In a display method on a display device in an NC machine tool,
The desired screen for each mode is displayed at the same time as each mode is selected, and after the display screen is updated, when the mode is newly selected, the updated screen is displayed. .

[Industrial application field]

The present invention is a computer-controlled NC machine tool (hereinafter referred to as C machine tool).
The present invention relates to display systems for NCs, and particularly relates to CRT display systems that reduce complicated key operations and can quickly switch to a desired screen, thereby improving operability.

[Problems to be solved by conventional technology and invention] Part 5
As shown in the figure, a CNC generally includes a machine tool 51 for processing an object, a servo motor and its mechanism 52 that operate the tools of this machine tool, and a command tape T.
A control unit 53 includes a microcomputer that controls the servo mechanism based on input signals from the servo mechanism to perform desired processing, an operation panel 54 includes a keyboard for commands to be sent to the control unit by an operator, and an operation panel 54 for automatic operation, etc. and a CRT display section 55 that displays the shape, coordinates, program, etc. of the object based on various modes.

When operating a CNC, there is an editing mode for automatic operation tape editing based on instructions from a command tape stored in internal memory, a manual operation mode,
There are many screen numbers corresponding to these modes, as shown in FIG. 4, which are searched and displayed on the CRT display. Switching to the desired screen, for example, switching to the one displaying the program on screen number 2 in the edit mode, may be performed by a high-power sequence using a high-power control circuit (not shown), but usually the operation panel This is done by manually operating the upper keyboard. That is, the operator selects a desired program display screen from among various screens.

However, when performing manual keyboard operations, when each of the above CNC modes is selected, unnecessary screens may be generated when selecting desired screens to be used within that mode as described above. Since the information is displayed sequentially, key operations are cumbersome and inefficient, and there has been a demand for improved operability by reducing the number of key operations.

[Means and operations for solving the problems] The present invention provides a CRT display system that solves the above-mentioned problems, and FIG. 1 shows a block diagram of the principle of the present invention. Reference numeral A denotes mode switching means, from which the operator selects automatic operation mode, tape operation mode, editing mode, manual mode, etc. B is a designated screen number selection means that automatically selects and outputs the screen number to be displayed for each switched mode. In this case, if the screen is not updated, which will be described later, the screen to be displayed when the mode is switched is specified in advance for each mode, so that it can be immediately displayed on the display means. On the other hand, C is a screen number switching command means, which is operated when it is desired to update the display screen, and is usually provided on the keyboard. When there is a screen update command, the screen update judgment means determines whether the number is a new display screen, and if it is correct, an update command is issued and the contents of the designated screen number selection means B are also switched to this new display screen. The updated screen will be displayed automatically.

〔Example〕

FIGS. 2 and 3 are flowcharts of an embodiment of the CRT display method of the present invention. FIG. 2 shows a case where a screen with a pre-specified screen number is displayed as is, and FIG. 3 shows a case where the display screen is updated. In FIG. 2, first, a desired mode is selected from each mode, ie, automatic operation mode, tape operation mode, editing mode, manual mode, etc., by keyboard operation (step 21). In this case, if the edit mode is selected, for example, by specifying the display of screen number 2 in advance, only the specified screen number 2 will be selected (step 22), and the CRT display will display the specified number. A screen is displayed (step 23)
.

FIG. 3 is a processing flowchart when updating the display screen, and when it is desired to update the previously specified screen number Dl, for example, screen number 2 for displaying a program, to another screen number DI11.

For example, when it is desired to switch the display screen to screen number 1 in the editing mode, this occurs in actual use. In this case, first, a command is given to switch the screen number to a desired screen number (step 31). This is done by keyboard operation. Next, it is compared with the previous screen number and it is determined whether or not to update to the new display screen number (step 3).
2), in the case of updating, the original screen number is updated to a new screen number (step 33), and the updated content is displayed via the aforementioned specified screen number selection means (step 34) (step 35). ), and the subsequent processing is performed according to the flowchart in FIG. Also, another mode may be selected next and you will return to this mode, but in this case the Q
The subsequently updated screen number Dm is automatically selected, and the process is performed according to the flowchart of FIG. 2 described above.

〔Effect of the invention〕

As explained above, according to the present invention, when various modes are selected, a desired screen can be quickly displayed, thereby improving the operability and cumbersomeness of the keyboard. In particular, in the case of high-mix, low-volume production, mode switching and display screen updating are frequently performed, so this effect is very significant.
